I concur, if you can get surgery, go for it! And who knows, it might be able to be done the minimally i nvase way and not be as bad as you think!
Like the thoracic surgeon told my mom, he said if they did not think s urgery could prolong her life drastically or save her life, theywould say go on a cruise, nothing we can do. But if they have to make her sick for a few months to get her better, so be it I ohpe that makes sense
